Frequently asked questions

Can the computer be beaten?

A perfect Tic Tac Toe player never loses, but the CPU leaves openings, so look for fork opportunities where you create two winning threats at once.

What is the best opening move?

Taking a corner gives you the most ways to build a line. The center is also strong because it touches the most winning paths.

Can two people play on one device?

Yes, the two-player mode alternates turns on the same screen, which is perfect for quick games on phones.
